Abstract

High-resolution solid-state carbon-13 nuclear magnetic resonance spectroscopic studies of a chemisorbed molybdenum hexacarbonyl fragment on γ-alumina are described. It is shown that chemical shift anisotropy information, obtained by analysis of spinning sideband intensities in magic-angle spinning spectra, can be used to study the mobilities of chemisorbed metal carbonyl fragments. Evidence is presented for very facile rotation of a Mo(CO)5(ads) species about the surface-Mo bond.
